Atlantic Ocean hiding global warming?

For many years now a few scientists have been trying to convince people that humanity is causing too much carbon dioxide (CO2) to be released into the atmosphere, and that this is causing global warming.  The problem with this theory is that the global temperatures have not increased since 1998.

It's gotten to the point that global warming activists had to come up with an excuse to explain the heat that didn't happen.  They are now claiming the ocean ate it; that it is hiding 700 feet below the surface.

This past week scientists released a study that explains where all the global warming has gone.  They say that it has been being sucked into the Atlantic Ocean, and is hiding about a mile down.  It's a natural occurring event that goes in cycles, and explains why the atmosphere is not warming.

The problem with this is it doesn't make sense, because warm air and warm water rise.  If you go down a mile under the ocean it will be cold.  If you want to feel warm water, you will go to the surface, where the water is warmed by the sun.  

Instead of spending their time and money trying to prove global warming, maybe it's time these scientists accept the notion that mankind is not causing it.
